Israeli Foreign Minister Shimon Peres is expected to address the assembly Nov. 15.
Harris said his group plans to meet with the foreign ministers of Egypt and Jordan, as well as Joschka Fischer, the German foreign minister who played a key role in arranging a temporary Palestinian cease-fire last summer.

The Conference of Presidents of Major American Jewish Organizations will meet with the leaders of Romania and Ukraine while they are in New York for the assembly, executive vice chairman Malcolm Hoenlein said.

The U.N. assembly was expected to focus largely on Israel, its treatment at the early September racism conference and the prospects for peace in the Middle East.
